12.10 Nginx访问日志
12.11 Nginx日志切割
12.12 静态文件不记录日志和过期时间
12.10 Nginx访问日志
除了在主配置文件nginx.conf里定义日志格式外，还需要在虚拟主机配置文件中增加
[root@jimmylinux-001 vhost]# vim test.com.conf
重新加载配置文件后测试
[root@jimmylinux-001 vhost]# /usr/local/nginx/sbin/nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful [root@jimmylinux-001 vhost]# /usr/local/nginx/sbin/nginx -s reload
12.11 Nginx日志切割
Nginx不像Apache有自带的日志切割工具，所以需要借助于系统的日志切割工具或者自己写日志切割脚本。
1、创建一个shell脚本
[root@jimmylinux-001 vhost]# vim /usr/local/sbin/nginx_log_rotate.sh 写入以下内容 #! /bin/bash d=`date -d "-1 day" +%Y%m%d` logdir="/tmp/" nginx_pid="/usr/local/nginx/logs/nginx.pid" #! /bin/bash d=`date -d "-1 day" +%Y%m%d` logdir="/tmp/" nginx_pid="/usr/local/nginx/logs/nginx.pid" cd $logdir for log in `ls *.log` do mv $log $log-$d done /bin/kill -HUP `cat $nginx_pid`
[root@jimmylinux-001 vhost]# sh -x /usr/local/sbin/nginx_log_rotate.sh sh运行脚本，-x表示查看执行脚本的过程。 ++ date -d '-1 day' +%Y%m%d + d=20180607
+ logdir=/tmp/
+ nginx_pid=/usr/local/nginx/logs/nginx.pid + cd /tmp/
++ ls test.com.log + for log in '`ls *.log`'
+ mv test.com.log test.com.log-20180607
++ cat /usr/local/nginx/logs/nginx.pid + /bin/kill -HUP 1049
以上就是日志切割的脚本，长此以往每天都会生成一个日志，除了每天切割之外还需要做一个清理，可以执行如下命令清理。
[root@jimmylinux-001 vhost]# find /tmp/ -name *.log-* -type f -mtime +30 |xargs rm rm: 缺少操作数 因为没有满足条件的文件，所以会报错提示“缺少操作数” Try 'rm --help' for more information.
2、加一个任务计划
[root@jimmylinux-001 vhost]# crontab -e 加一个任务计划 0 0 * * * /usr/local/sbin/nginx_log_rotate.sh 每天的凌晨0点开始执行
12.12 静态文件不记录日志和过期时间
在Apache配置的时候介绍了静态文件可以设置不记录日志的，那么在Nginx里面同样也可以把一些静态文件忽略掉，不记录日志。
1、编辑配置文件test.com.conf
[root@jimmylinux-001 vhost]# vim test.com.conf 添加以下内容 location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ 匹配URL里面的关键词，括号里面的|是或者，.\是脱义的意思。 { expires 7d; 过期时间7天 access_log off; } location ~ .*\.(js|css)$ { expires 12h; access_log off; }
2、重新加载配置文件后模拟一个图片
[root@jimmylinux-001 vhost]# /usr/local/nginx/sbin/nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful [root@jimmylinux-001 vhost]# /usr/local/nginx/sbin/nginx -s reload
[root@jimmylinux-001 vhost]# cd /data/wwwroot/test.com/ [root@jimmylinux-001 test.com]# ls admin index.html [root@jimmylinux-001 test.com]# vim 1.gif 新建一个1.gif文件 [root@jimmylinux-001 test.com]# vim 2.js 新建一个2.js文件 [root@jimmylinux-001 test.com]# curl -x127.0.0.1:80 test.com/1.jif <html>
